Abstract

AAS are being used widespread in order to improve athlete's performance, due to its capacity to improve muscle mass and strength, furthermore, recent studies showed a diffuse abuse by adolescents for libido reasons and appearance. Nandrolone is one of the most abused AAS in the world, it has a similar structure and chemical characteristic compared to testosterone. It interacts with different receptors in our body, such as estrogen, progesterone and testosterone, that's why Nandrolone side effects affect the whole human body. Differents proteins and genes are involved in testosterone biosynthesis of testosterone, with different regulatory pathways. In this review we focused on nandrolone related male reproductive system damage, in order to show the heavy consequences of AAS abuse. Nandrolone regulates MMP-2 and it could lead to spermatogenesis impairment. Oxidative stress and increase of Ros production could play a leading role in Nandrolone related infertility. Different oncogenic pathways are activated by Nandrolone and more studies need to be done to clear up correlations between this molecule and cancer. Leydig cell testosterone production is influenced by Nandrolone, moreover it was demonstrated to be a dose-dipendent mechanism, despite multiple proteins and genes involved in this process were discovered, other regulatory proteins, genes and pathways, need to be studied in deep.
